The Ovigers arise ventro-laterally, close to the angle formed by the cephalon and 

 the first lateral process. They are extremely small, and it is open to question whether 

 they are mature or not. As the removal of one of these appendages involves serious 

 risk to the only specimen, it cannot be very satisfactorily described. Not less than 

 six joints can be distinguished, the first three of which are very small. A small body- 

 process from which the appendage arises may be an additional joint. The terminal 

 joint is the longest, it is rounded at the extremity and does not carry any trace of a 

 claw, nor are setae of any kind discernible. 



With regard to the Legs, the first coxa has already been alluded to as the largest 

 of the three, the other two are very little if any shorter, and the second is dilated 

 distally. It is difficult to get the limb in one plane for measurement, and the 

 joints appear subject to some variation. The proportion of the joints appears to be 

 3'5 : 3 : 2'5 : '5 : 2 "5. The femur is stout, and the two following joints decrease in 

 calibre. The limb bears a very few scattered setse, most numerous on the second 

 tibia. The tarsus is very small and cup-like, with two or three spinous setse 

 ventrally ; the propodus is proportionately long, slightly curved, and bearing a few 

 setse. On its ventral margin it carries a row of setse, but there is nothing very 

 distinctive about them. The claw is short and stout, and is accompanied by two 

 slender auxiliaries. 



The only example of this peculiar species is a female, and the Genital apertures 

 are found in the middle of the second coxse of all the legs. 



Taken by the dredge in Winter Quarters before the ship was frozen in. Ten 

 fathoms or less. 



AUSTEOEAPTUS. 



Body with spurs on the lateral processes and first coxsb. Segmentation very imperfect. 



Proboscis stout at the base, terminating in a point. 



Chelifori rudimentary. 



Palps 6-jointed. 



Ovigers 10-jointed, without terminal claw or denticulate spines. 



Legs comparatively long, terminal claw with two auxiliaries. 



AUSTROKAPTTJS POLARIS. 



(Plate VIII., fig. 2.) 

 Specific characters : — 



Body rather stout, with prominent spurs on the lateral processes and the first coxse. 

 Proboscis half the length of the trunk, pointed. 



Palp 6-jointed, the terminal joint is twice as long as its predecessor, and articulated at an 

 angle to it. 



Oviger 10-jointed, without terminal claw or denticulate spines. 

 Legs long, terminal claw with two small auxiliaries. 



The body is rather robust, with long lateral processes which arise close together 

 and diverge considerably. These are provided dorsally with a pair of stout tubercular 

 spines which exist also on the first coxse, where they are greatly exaggerated.
